I don't think it's impulsive to buy what you need. I tend to "impulsively" shop when I am feeling lonely. But I usually do not get things I need, but more often clothes that make me feel pretty or pretty shoes or purses and stuff like that. I try to stay on a tight budget, but usually just blow it every once in awhile. Almost always, because I feel lonely. But sometimes I am just jittery and unsettled for no reason I can put my finger on. However, every time I impulsively shop, afterward, I slow down and try to ask myself "what's really going on here?" but it always seems to be "after the fact".
